AIMS To evaluate the effects of adding glucagon-like peptide-1 (GLP-1) analogue therapy to insulin on glycated hemoglobin (HbA1c), weight, insulin dosage, treatment satisfaction, and risk of hypoglycaemia. 

METHODS Type 2 diabetes patients with insulin therapy receiving a GLP-1 analogue at 4 Swedish centers were studied. Hypoglycemia was evaluated using glucometers and patient self-report. The Diabetes Treatment Satisfaction Questionnaire (DTSQ) was used to evaluate treatment satisfac.

RESULTS Among 65 patients studied, 4 discontinued therapy, none due to hypoglycemia, and there were no suspected severe adverse events. Among 61 patients who remained on therapy over a mean of 7.0 months, 40 were treated with liraglutide and 21 with exenatide. HbA1c decreased from a mean of 8.9% (82.4mmol/mol) to 7.9% (71.9mmol/mol) (p<0.001), weight decreased from 111.1kg to 104.0kg (p<0.001) and insulin doses were reduced from 91.1U to 52.2U (p<0.001). There was one patient with severe hypoglycemia. The mean number of asymptomatic hypoglycemia per patient and month, reported for the last month (0.085 below 4.0mmol/l and 0 below 3.0mmol/l) and documented symptomatic hypoglycemia (0.24 below 4.0mmol/l and 0.068 below 3.0mmol/l) was low. The DTSQc showed higher treatment satisfaction than with the previous regimen of 11.9 (scale -18 to +18 points, p<0.001).

CONCLUSIONS The addition of GLP-1 analogues to insulin in patients with type 2 diabetes is associated with reductions in HbA1c, weight, and insulin dose, along with a low risk of hypoglycemia and high treatment satisfaction.
